Stealer of Secrets

The plainest possible printing of the combat-damage-equals-card-draw effect, and the baseline rate against which every wilier version gets measured. The job is simple: connect once, refill once. But a 2/2 for three with no evasion and no other text is fragile enough that connecting is the whole problem, and that fragility is also the point. Designs built on combat-damage card draw live or die on whether the attacker can reliably get through, and this one carries nothing to help it through blockers: it has to be pushed past them by other means rather than carrying itself. Compare what the same trigger looks like when stapled to a creature that does the work alone: Thieving Magpie pays a mana more for flying and stops needing help, while Ophidian and its descendants traded the attack step for tapping instead of swinging. Stealer of Secrets keeps none of that connective tissue, which is exactly what makes it a clean unit of the mechanic: it draws if it hits, and nothing on the card promises it will. The interesting design lever sits off the card, in whatever is granting it unblockable or trample or menace. As a study in the bare Curiosity-on-a-stick template, it is honest about the deal: cheap, repeatable card advantage gated entirely behind the single hardest thing to guarantee in combat.
